Man hurls explosives inside Shanghai airport injuring four passengers

A man hurled a bottle containing home-made explosives inside the main international airport in China's commercial hub of Shanghai yesterday, injuring four people before attempting to kill himself, authorities said.

The unidentified man removed a beer bottle or bottles with explosive materials from a backpack before throwing one near a check-in counter in Terminal Two at Pudong International Airport, the Shanghai government said in a statement.

He then took out a knife and slashed at his neck, it said, adding the man is now in critical condition in hospital.

His motive was not disclosed. There have been several cases in China of disgruntled individuals setting off explosions or starting fires in revenge for perceived wrongs.

Four passengers were injured in the incident, said the statement on the Shanghai government's official microblog.

The official Xinhua news agency said they included a man from the Philippines, as well as a 67-year-old man and a 64-year-old woman -- both described as Chinese. The nationality of the fourth victim was unclear.

The four were slightly injured by glass shards and are being treated in hospital, it added.
